5.1.2.14.1 User menu lockout
If the Front Menu Lockout is enabled the user may not manually initiate any User mode from the
control panel. The User Menu Lockout setting is accessed from the Control panel Locks menu by
typing “8” on the RS-232 terminal. To navigate backwards, use the <Esc> or “Q” key on the RS-232
terminal.
5.1.2.15 Assume Low-End calibration
The Assume Low-End Calibration range code (Zero Calibration Range in the setup menu) allows the user
to set the range of acceptable LOW calibration gas for the Model 7100E two-point calibration system.
During calibration, the Model 7100E analyzer will automatically recognize an applied calibration gas as a
LOW range calibration gas if its oxygen concentration is within the range set by the Assume Low-End
Calibration range code. Refer to section 3.2.1 for a detailed explanation of the calibration system.
Assume Low-End Calibration range can be set to 0 (single point calibration) • 3 (0-5 PPM) • 4 (0-50 PPM)
• 5 (0-500 PPM). The Assume Low-End Calibration setting is accessed from the Setup Main Menu by
typing “9” on the RS-232 terminal. To navigate backwards, use the <Esc> or “Q” key on the RS-232
terminal.
5.1.2.15.1 Calibration mode auto return to RUN
This setting determines the minimum time that the Model 7100E allows after exiting from control
panel or service port user menus, before returning the unit to on-line status. The calibration mode
auto return setting is accessed from the Control panel Locks menu by typing ”T” on the RS-232
terminal. To navigate backwards, use the <Esc> or “Q” key on the RS-232 terminal.
